Deposit on the EE-101 Stand-Alone Phono Preamp Kit (EE101D) - $125+$7 shipping (48 states)

EE-101 Stand Alone Phono Preamp front view

THE EE-101 is a stand-alone version of the PHONOZ phono section. It includes a regulated power supply, an internal toroidal power transformer, a fused IEC power entrance connection, and a volume control. Like the GT-102 power amplifier, it includes a steel wall between the power supply and signal processing sections to drive down the noise.

If LP's are your passion this takes the place of a full preamp. Just combine it with your power-amp, turntable (moving magnet cartridge), and speakers, for some of the best sound you'll ever hear. Because it has the PHONOZ phono section, you get:

It's available as a complete kit for $249 plus $20 shipping (48 states). You can buy stand-alone phono preamps starting at $20 and running all the way up to $10,000. My belief is that this combination of performance, price, and features hits a sweet spot. I'll confirm this in the usual way, by making the EE101 available for pre-order. If we get 25 pre-orders by December 25, then it's a go, for delivery before the end of winter 2018. As always, if there isn't enough interest, then everyone gets their pre-order payment returned.

Please note that the amount you'll see at checkout is $132, that's $125 toward the total price of $249, and $7 toward the $20 of shipping (48 states). That leaves a balance of $132 due before shipping.

EE-101 Enclosure Without Phono Preamp(EE101NP) - $175+$20 shipping (48 states)

EE-101 enclosure internal view

This item is just the EE101 enclosure and power supply, without the phono preamp, thus the ordering code EE101NP. Order it now, for delivery at the end of winter 2018. The same delivery conditions apply as for the EE101...we need to get enough orders to make this go by December 25. If there aren't enough orders, then all payments will be returned.

The EE101NP kit includes the complete enclosure, with volume control, two gold-plated RCA phono jacks, +/-12 V power supply, power entrance connector, line cord, and fuse. It's a complete platform to host the PHONOZ preamp, if you already have one. It's also a great looking base for your own projects. The enclosed picture shows the inside of the prototype. In the actual product, we've shrunk the power supply board a bit to make more room for the AC power wiring. We've also cleaned up the power entry hardware, so everything will look a bit smoother than what you currently see.

EE-101 Enclosure, Just the Mechanical Stuff (EE101MECH) - $110+$20 shipping (48 states)

EE-101MECH enclosure

This item is just the EE101 enclosure and a few of the connector bits that make it a great base for your projects. It includes:

It doesn't include the power supply, volume control, knob, or RCA jacks. The picture is shown partially assembled, but some assembly is required.

This product is on pre-order status. Order now for late winter 2018 delivery. If we don't get enough orders, then everyone will get their prepayments back in early January.

Volume Control Kit for the GT-102 Amplifier (VC102) - $9.95

volume control kit installed into a GT-102

Note that the volume control shown in the picture above is not included in the standard GT-102 kit.

Most times, the GT-102 is used with a preamplifier. However, a small but growing group are dedicating a GT-102 to a CD player. In many cases, the CD player doesn't have a volume control, so adding the volume control to the GT-101 makes great sense. This kit has a quality stereo volume control, shielded cable, and an attractive knob. Installing the kit requires you to drill a hole in the front panel of your GT-102. Here's the Installation Manual for the volume control kit.

Gold Plated Input Connectors - $5.50

Note that the gold-plated input conectors shown in the picture above are now included in the standard GT-101 kit.

We offer gold-plated input jacks here in the Akitika store in case:

These connectors are gold plated. In addition, they have a handy hex on both sides. This makes it easy to tighten the connector in place. It also comes with insulating washers. If you replace the stock input connectors from an older GT-101 with this item, you should also swap out the stock insulating washers that come with the GT-101.

Your order contains two gold-plated chassis-mount RCA input connectors, one with a red id band (right channel) and the other with a black band (left channel). Both hexes use a 12 mm wrench for tightening. Of course, pliers will work in a pinch. The ground lug has an elongated hole that accommodates more than one wire, which is always useful. This is a great price for a great connector, and the hex feature makes assembly a breeze!

Separate Power Amplifier Components

Selling separate components began when a customer wanted to build a seven channel amplifier. He bought 7 amplifier modules, 3 power supply regulators, and 3 power transformers. The light-bulb over my head went on...Maybe lots of other DIY'ers would like to build special amp configurations in their own custom enclosures. By offering the modules and parts, everyone wins.

Assembly directions and schematics for the components may be found in the appropriate subsections of the GT-101 Assembly manual.

Single Channel Amplifier Module Kit (AMP101) - $49.00

one channel kit of parts Completed Amplifier Module

The kit includes circuit boards and parts to build a stand-alone amplifier module.It even includes thermal grease and mounting hardware, but it does not include a power supply, solder, or heat sinks. The recommended power supply voltage is a single 72 Volt DC supply. With a regulated 72 volt supply, the AMP01 delivers more than 50 Watts into an 8 Ohm load and nearly double that amount into 4 Ohms.

This is the same amplifier module used in the GT-101 Power Amplifier. It features top quality components FR4 circuit board, a huge 10,000 uF output capacitor, 1% and 0.1% metal film resistors,with film and COG capacitors in the signal paths.

This is a'll get the parts and the PCB. You must assemble it to get the completed module pictured above!

Assembly directions and schematics for the components may be found in the appropriate subsections of the GT-101 Assembly manual.

Power Supply Regulator Kit (PSR101)- $59.00

power supply regulator Printed Circuit Board power supply regulator Parts in a soup bowl

This linear regulator produces 72 Volts of quiet, clean, well regulated DC at 3.5 Amps DC, with more current available on a transient basis. All it needs is an appropriate transformer like the XFMR101 and a heatsink. The bridge, input, and output filter caps are all built in. Built-in safety features include a slow-start and current limiting fold-back that still allows high transient currents. Experts can void the warranty and modify the circuit to change the output voltage and current. The less adventurous can use it just like it is, and get great results.

This is the power supply module from the GT-101. It features top quality components FR4 circuit board, 1% and 0.1% metal film resistors for precise output voltage, and a big, beefy mosfet as the pass element in the regulator. It even includes heat sink compound, mounting brackets, and hardware. (Soup bowl not included).

Assembly directions and schematics for the components may be found in the appropriate subsections of the GT-101 Assembly manual.

Deep Finned Heatsink (HS101) - $20.00

It also has 6-32 mounting holes in the bottom that accept 6-32x3/8" screws to allow easy mounting on a chassis. The heatsink dimensions are 5.375"x 3.5" x 1.38". The distance between the bottom flange mounting holes is 3.875". This heatsinks is used in the GT-101.

230 VA 120/240 Volts Power Transformer (XFMR101) - $49.00

This beefy toroidal transformer, made by Avel Lindberg (part number Y236602) comes with mounting hardware. Its dual primaries can be wired for either 120V or 240V operation. It has two secondaries, making it suitable for single output or split supplies. With both secondaries in series, it produces about 106 VDC into a lightly loaded bridge rectifier arrangement. In a split supply it produces (lightly loaded) about +/-53 Volts. Avel Lindberg quotes the secondaries as 35-0-35 Volts RMS.

Specifications (unless otherwise stated, all specs are at 27 C)

1 kHz Oscillator with Just 2PPM Distortion (1KHZ2PPM) - $79.00

1 kHz 2 PPM oscillator with enclosure 1 kHz 2 PPM oscillator PCB and components

This oscillator has state of the art distortion performance, about 30 times lower than the less expensive 1 kHz oscillator shown above. This distortion is better than the best A2D's, D2A's, and sound cards. Typically, getting distortion this low would could at least $1000.

How do we do it? Well, start with a really careful layout. Make sure you groom where all the nonlinear currents go. Bypass the power supplies well. Use only the highest performing op-amps. Use a high selectivity topology with low distortion. Top it off with the oldest trick in the incandescent lamp used to provide the perfect balance of positive and negative feedback and LOW distortion! The only way you can get lower distortion is with an Audio Precision oscillator. The only way to measure the distortion is on an Audio Precision Distortion Analyzer in FFT Residual mode.

It has stereo RCA outputs and a level control. It also runs from a pair of 9V batteries (not supplied), and has an LED power light. The specs:
